It would be nice to update the docs then. Which mode classes are allowed in 
an expression? (The list of modes in the docs is not up-to-date either, it 
lacks the vector modes).

MODE_RANDOM: no.
MODE_INT: yes.
MODE_FLOAT: yes.
MODE_PARTIAL_INT: yes?
MODE_CC: no?
MODE_COMPLEX_INT: yes?
MODE_COMPLEX_FLOAT: yes?
MODE_VECTOR_INT: yes?
MODE_VECTOR_FLOAT:yes?
